IE, you mean the internet browser from IE4-6 that has shell integration with Windows Explorer and becomes unstable, if it is removed?
Eww
"
Internet Explorer removal has changed over its version history, but the nature of many of its upgrades and installation methods have been a matter of public interest. The first version to be included was version 2 with Windows 95 in late 1996. Later, users who upgraded to IE3 (which came out in 1996), could still use the last IE, because the installation converted the previous version to separate directory.
However, Internet Explorer 4 created a controversy with its shell integration with Windows Explorer, and with later versions removal (or inability to do so) became more complicated. The idea of removing Internet Explorer from a Microsoft Windows operating system was proposed during the United States v. Microsoft case. Later, some security advocates took up the idea as a way to protect Windows systems from attack via IE vulnerabilities. By the release of Internet Explorer 7, some of the shell integration began being reduced, such as changing ActiveX hosting and a different look than Windows Explorer.
As of build 7048 of Windows 7, Microsoft added the ability to safely remove Internet Explorer from Windows.[2] Dependencies such as the Trident layout engine are not removed through this process, but the Internet Explorer executable (iexplore.exe) is removed without harming any other Windows components, thus preventing Internet Explorer itself from running. It was proposed that a special version of Windows 7, Windows 7 E, would be shipped without Internet Explorer in Europe as a result of EU antitrust investigations against Microsoft.[3][4][5][6][7] However, in July 2009, Microsoft cancelled the Windows 7 E editions due to negative reactions from computer manufacturers."
